"Any time he goes to attack and his target is not in melee range he will do his ranged attack which is a 360 AoE hope wipe roar. It is critical that the tank get into melee fast and stay there, even while the rest of the group is dealing with the overseer. When he gets punted away he needs to run back fast.

I think the only scripted hope wipe is after you kill the overseer and open the door to come back into the balrog room. The roar can also be BPEd so you can use pledge and other skills to avoid getting your hope stripped."
